== DEPENDENCIES ==
=== HARPY ===
	$ cabal install harpy

=== HS-JAVA ===
for `hs-java' a patched build is needed:
	$ git clone git://wien.tomnetworks.com/hs-java.git
	$ cd hs-java
	$ git checkout -t origin/v0.2
	$ cabal configure; cabal build; cabal install
hint: for some unknown reason yet, it seems building from source will be easier
if you first install `hs-java' via cabal (like `harpy' above)

=== CONTROL-MONAD-FAILURE ===
we had some issues with building this package (it's a dependency of `hs-java').
If you also encounter problems like this:
> [3 of 4] Compiling Control.Monad.Exception.Base ( Control/Monad/Exception/Base.hs, dist/build/Control/Monad/Exception/Base.o )
>
> Control/Monad/Exception/Base.hs:117:60:
>     Not in scope: type constructor or class `WrapFailure'
>
> Control/Monad/Exception/Base.hs:118:2:
>     `wrapFailure' is not a (visible) method of class `WrapFailure'

then try
	$ cabal install cabal-install
	$ export PATH=~/.cabal/bin:$PATH
after that, try again your previous step (e.g. `cabal install hs-java')



== NOTE ==
unfortunately, many haskell libaries arn't tested very well, so building
libraries from hackage can be a very painful trip.

a system configuration we had success building all required
libraries (yes, no x86_64 so far!):
